Bedrock more feature adding

I am a bedrock modding and currently is using the latest version of mcreater.

But to my surprise , more than 50% things are not supported in bedrock addon.

I indesprate requires the trigger section seen in my mid element but is showing NOT SUPPORTED

How can I use every features for my bedrock modding . Is there any plugin to make features supportive . Or when will mcreater update to provide support to bedrock just like to the Java modding.
